Hi all, Been a looooong time since I posted on photo.net. I'm going to embark on an effort to eat up my remaining IR stock. HIE and EIR in 135, Konica, Efke, and Ilford in 120. My question is on metering. My notes on my technique are not clear from when I was last shooting IR a few years ago, and searches give me confusing answers. I'll try to keep my question direct. Let's take Konica 750. What do I set the meter at, when metering without a filter? I will be using a Hoya R72 filter, but the camera I'm using at least for medium format has no meter, so I'll be using a spot meter, probably (just what I have handy - I might pick up an incident meter). I know I have to bracket. Suggestions? I have EI "30-50" in my notes but that has to be before the filter factor, yeah? So I'd drop 5 stops to account for the filter? I've read of Konica being in the single digits so that actually makes sense. Hope that makes some sense. Appreciate the help.
